First off, I want to thank the user symbols for gifting me this absolute lad whom I love very much. Go gift them please!
The pet is a funky interdimensional chaos being sort of along the lines of Bill Cipher except less evil. They live in a tent on a weird space cloud with their two friends Pinkey and Evelyn. They do not have a name. They exclusively own orange and purple stuff, whether it be clothing or accessories or their tent, and enjoy making intricate homemade beverages. They have a loud and boisterous personality, which is easily learned via their very loud, very big voice. They communicate by speaking through people's minds despite having a mouth, and can see using some sort of very advanced echolocation. As far as anyone knows, they do not eat.
Pinkey (the little ghost) was accidentally created by our dimension-shifting friend one day a long time ago. They are very shy and also worry a lot.
Evelyn (the egg) was found on a similar cloud one day by the other two. She cannot speak (no mouth), but she can write with her feet, and has excellent cursive. She cannot see either, but doesn't really need too, since she can alter her environment at will using her weird powers that are akin to a less powerful version of no name fella's.
